In 1978 for one at bat, in one game, the 6'5 , 230 lb. Dave "The Cobra" Parker wore a hockey goalie mask for what has to be the most menacing sight ever witnessed inside a ballpark.
From the back of the card:
July 16,1978: After suffering a broken jaw in a collision with Mets'catcher John Stearns on June, 30, Dave Parker returned to the Pirates'lineup well ahead of schedule to take on the Padres. To protect hisnewly healed jaw Parker purchased a goalie mask at a sporting goodsstore. Parker cut, painted and padded the mask himself to fit the contourof his face. Perhps intimidated by his appearence, the Padres intention-ally walked him that day.The hockey goalie mask only lasted the one game with Parker switchingto a football facemask affixed to his batting helmet that he wore only forbase running.
I though it would be a cool idea to put the image of Parker in the goalie mask on a 1978 Topps style hockey card. I thought it made the most sense to go with the color scheme used on the Penguins' cards for '78.
